Abstract: The connector device comprises a male plug and a female receptacle, each of which has a housing with a central tubular component and a cavity extending therethrough and adapted to receive an end of an electrical conduit. Both the plug and receptacle include means for aligning the electrical pathways therein and for sealing the conduits, plug and receptacle against elevated temperature and corrosive gases, etc. The central tubular components are electrically insulated. The male plug has a plurality of spaced parallel connector pins extending forwardly from the front end of the plug's tubular component and spaced inwardly of a plug sleeve. The receptacle tubular member is disposed within a sleeve and carries a pin receiver on the front end thereof, which receiver bears a plurality of spaced parallel passageways extending longitudinally of the tubular member and containing electrical connectors therein for interconnection with an electrical conduit at the rear of the female receptacle.

Abstract: Connector for tow cable which carries tow tension and electrical circuits permits release of both the tension and the circuits. Electrical connectors in high current circuits are arranged so that the male connector is pulled out of the female electric socket, and the arc between them is elongated, but the arc chamber is closed until the arc is extinguished.
